The figure shows a relation from set A to set B.
The range of the relation is:
{1, 2, 3, 4, 5}
{a, b, c, d}
{ (a,1), (b,1), (c,4), (d,2) }
{1, 2, 4}
Given the function f(x) = x2 − 5x − 6 the value of f(2) is:
0.
-12.
20.
12.
Given the function, f(x) = 1 - 2x. The value of f(-3) is:
-7.
7.
-5.
5.
The mapping represented in the figure is:
Many – Many.
1 – 1.
Many – 1.
1 – many.
Given the function f: x ⟼ 2x − 3, the inverse function is:
(x - 2)/2.
(x - 3)/2.
3x/2.
(x + 3)/2.
